ALBERT M. BO\VERS, OF YEVARK, NEW JERSEY.

STEAM-HEATED ROLLER.

EPECIPICATION forming part of Letters Patent No. 339,735, dated April 13, 1886.

Application filed August 29, 1885. Serial No. 175,614.

such as will enable others skilled in the art to which it appertains to make and use the same, reference being bad to the accompanying drawings, and to the letters of reference marked thereon,which form a part of this specification.

In said drawings, Figure 1 is a side elevation of a roller embodying my invention. Fig. 2 is a longitudinal section of the roller shown in Fig. 1, and Fig. 3 is an end elevation of the roller.

The invention is designed to provide a roller adapted to be employed in pebbling or finishing leather, forlaundry purposes, or for other objects for which it is applicable, that may be heated to any desired degree and maintained thereat with but little trouble and expense, said invention consisting of two principal parts, and outer revolving portion or roller, and an inner portion or heater,preferably stationary in relation to the roller, substantially as illustrated in the drawings and described and claimed hereinafter.

As referred to briefly above, the heated roller is composed of an outer hollow portion or roller, a,which bears directly upon theleather, havingjournals b, asindicated in Fig. 1, and an inner radiator, c. The roller a may be smooth or engraved, or treated in any suitable manner to produce any design or mark upon the leather, as desired.

Vithin the roller or hollow portion a is arranged the heater or radiator, which, in the device shown for the purpose of illustration, consists of a shell, 0, having caps (I, screwed upon the ends thereof, and hollow threaded tubes 6 c',screwed into the end caps, as shown in Fig. 2.

The journals 1) of the roller are bored, and a piece of wood, f, or otheranti-friction material or metal countersunk in the end thereof, the diameter of the borein the journals being larger than that of the tubes 6 e, which extend therethrough, and also through the pieces f, the

(No model.)

bore in the pieces f being about the same diameter as the tubes.

The tubes e c extend out beyond the ends of the journals, and are preferably threaded to receive fittings through which the steam is conducted into and through the heating-shell c, the steam entering one tube and passing out through the other.

The fittings g, or pipes, which may be attached to either or both tubes 6 e, are illustrated in the drawings, Figs. 1 and 2, and to these are attached flexible tubes h, which permit the requisite amount of movement of the roller when in use.

To provide for the insertion and removal of the heating-shell,&c.,I form one end of the roller with a removable plug, i, which is secured in position by screws j, as shown in Fig. 2.

As will be understood, the outer portion or roller, a, turns as it is moved to and fro over the leather, the heater or radiator and tubes 6 6, attached thereto, remaining practically stationary in relation to the roller, the pieces f constituting anti-friction bearings upon the tubes e c.

This heated roller may be used in ironing collars, cuffs, &c., in a laundry where steam can be had, but is designed principally for use in leather-finishing machines, one of which is illustrated in a contemporaneous application.

This method of heating the roll by radiation is more advantageous than the introduction of steam directly into the roller, as it can be more easily controlled, the temperature increased or diminished, as desired, and is particularly adapted for lower temperatures.

I am aware that ironing-rolls and rolls for other purposes have been heated by the direct application of the heat to the roll itself, as when heated by a gas-jet or by steam; hence it is not' my intention to claim, broadly, a heated roll without reference to the means employed. \Vhen heated by steam heretofore,it has been necessary to use stuffing-boxes to provide a steam-tight j oint; but this would be impracticable for the purpose to which I intend to apply it, and in fact is a great disadvantage for any purpose, since this construction isliable to allow the escape of water, which would seriously injure the leather or other material to be ironed.

combination, .a hollow' roller having bored journals, one of which forms a removable plug. substantially as specified, and a steam-heated radiator arranged within said roller, having tubes connected with said radiator, which ex- 20 tend through the bored journals, for the purposeset forth. Y

In testimony that I claim the foregoing I have hereunto set my hand this 21st day of August, 1885 ALBERT M. BOWERS.
